it has for its object an appliance for lifting and positioning invalidsand for raising, lowering or moving into different positions above the ibed for the purpose of resting, and various purposes, and of changingthe position of the body and limbs, and in case of broken limbs,and

for bathing, and with the least possible annoyance or injury tothepatient, and also for carrying the invalid from room to room, and toenable the patient to assume different positions, such as sitting, orreclining, and by this device the patient may be handled free andindependent of the bed, and moved from one side of the bed to the otherin restful position without manual contact with the patient, and also toenable the patient to be placed in a sitting position with the limbsresting horizontally upon the bed,

and to enable the patient to be easily handled by one person. I

With these objects in view my invention consists of the following novelfeatures of construction and arrangement of parts as will-be hereinafterfully described and set'forth in the claims.

Fig. 10 is aside view of a detailed part of my 'device' Y Fig. 11 is afragmentary part of my device partly in cross section.

Referring to the drawings, A designates a frame structure having a pairof triangular shaped end portions a, a, comprising side bars 2, 2, and ahorizontal cross bar 3; The side bars 2-, 2, of each end portion may besecured together at their upper ends in any suitable manner, while theirlower ends are spaced apart and joined to the cross bar 3. Castors 4, 4,are provided on the bottom surface of each side ..bar 2 for thepurpose-hereinafter explained. A

triangular shaped end plate 6 is arranged between each pair of side bars2, 2, at the apex of each end-portion a, a, and these plates areprovided with-suitable openings to receive the opposite ends of a pairof horizontal rods or shafts 5 and '7. The rod-3 has its opposite endsfixedly secured to the plate 6 at the apex of the triangular endportions (1, a, while the lower or rotatable shaft 7 has its oppositeends journaled in suitable openings at the lower portion of the endplates 6. In order to stiffen the frame structure, I provide suitablebraces 10, each of which has one of its ends secured to a side bar 2 andits other end fixedly secured to the shaft 5.

A plurality of spaced central pulleys 11 are rigidly mounted on therotatable shaft 7 and adapted to rotate with the latter.

At spaced points along the shaft '7, where the respective centralpulleys 11 are mounted, I provide triangular shaped transverse spreadersupports 12. Each of these supports consists of a pair of spacedparallel horizontal bases 13, and two pairs of spaced parallel side bars13'. These supports are connected to the rod 5 and shaft '7 by means ofa pair of spaced vertical parallel arms 8o 12, each of which may beformed integral with the base and side arms of the support, as shown inFig. 3. The upper and lower portions of each armare provided withopenings to receive the shafts 5 and '7, and in this manner the supports12 will be held in rigid position on the rod and shaft Band 7respectively. A side pulley 11' is arranged at the lateral extremitiesof each spreader support 12 and is provided with the usual shaft, (notshown) which is journaled in suitable openings in the ends of eachhorizontal base 13.

On each of the central pulleys 11, I removably secure lifting tapes 14.One of the tapes on each central pulley is attached to' the undersurface of the latter, and extends outwardly over one of the sidepulleys 11 of that particular support, whereas the other tape is securedto the upper surface of the central pulley and extends outwardly in theopposite direction over the other side pulley 11' of the support, asclearly shown in Fig. 3.

A spreading bed frame B comprising a stretcher C of canvas or the like,is adapted to be raised in 9, for receiving the threaded pins 20 whichproject from the ends of the bars 18. In order to provide an adjustablemeans for stretching the canvas tightly, I furnish each end bar 18 withferrules Z), and threaded pins 20. The inner end of each pin extendsinto an opening in the end of the l8, and its outer end is adapted toproject through an inner nut 18 within the ferrule b, and into theopening of the side bar 16. A nut 03 is mounted on the outer threadedend of each pin 20, and when this nut is turned in a certain direction,the side bars 16 will be forced away from the end bars 16, therebystretching the canvas to the esired extent.

lower ends of the tapes 14 can be connected to the sides of thestretcher frame by means of snap fasteners 15, and it is obvious thatwhen the shaft 7 is turned, the tapes will lift the stretcher frame. Theshaft may be turned, as shown in Figs. 1 and 9, by a crank 8 having ahandle 9, and may be held in adjusted positions by any suitable devicesuch as a ratchet and pawl mechanism 9a.

Instead of connecting the crank handle directly to the shaf I may usethe construction shown in Figs. d, 7 and 8. In this arrangement, agearing mechanism G comprises a large gear 30 fixed to the shaft 7 andarranged at one side of one of the end plates 6. This gear meshes with asmaller gear 31, which is fast on a crank handle operated shaft 32 whichis journaled in the plate 6. A ratchet wheel 33 is also fixed to theshaft 32 and cooperates with a pawl 34 which is pivoted on the plate 6and is held in engagement with the ratche wheel by a spring 36 which hasone of its ends connected to the pawl and its other end connected tosaid plate 6. A handle 35 is fixed to the pawl for use in releasing itfrom the ratchet wheel.

In the embociment of the invention illustrated in Figs. 5, 6 and 9, theends of the tapes are connected to the stretcher frame B by snapfastenings 33a, and it will be noted at the head end of the frame, Ihave designated the straps by the numerals 29. These straps may beconnected to the upper portion of a pivoted head rest E by means of snapfastenings 33b.

The upper end portion of the head rest may also be connected by chains340: having snap fasteners 35a, with loops 33a on the side bars of thestretcher frame. When the parts 35a and 33a are connected, it is obviousthat the straps or tapes 29 will lift not alone the head rest, but thehead portion of the stretcher frame.

I prefer to provide the head rest with a frame 26 consisting of an endbar 25 and side bars 27, and if the head rest is formed of a canvassheet or the like, the pivotal joint may be made by sewing its loweredge to the canvas sheet C by a line of stitching as indicated at 28.

In order that the apparatus may be used with a bed pan, a suitableopening D in the canvas sheet C may be combined with a swinging flap 21that can be held in closed position by any suitable fastening devices22.

When a patient is transported, the flap 21 may be reinforced and held inclosed position while supporting the patient by means of a canvas cradleF which extends beneath the stretcher frame at the point where the flapis located. When the cradle F is used, it may be secured to the lowerends of the middle one of the straps 14, as indicated Fig. 6, and forconvenience in disclosure, I have marked these straps 29b in Fig. 6.

Whenever it is desirable to lift the head rest as indicated in Fig. 9,the straps 29 can be removed from their side pulleys 11 and wound ontheir central pulley to shorten the same as indicated in Fig. 9, andthen the straps can be again trained over their side pulleys and beattached to the head rest by the snap fasteners as indicated in thatfigure.

From the foregoing it is believed that the construction, operation andadvantages of the invention may be readily understood by those skilledin the art, and it is apparent that changes may be made in the detailsdisclosed, without departing from the spirit of the invention, asexpressed in the claims.
